This study is to clarify the drying shrinkage and shrinkage cracking characteristics of steel chip reinforced cementitious composite (SCRCC). In this study, free shrinkage of SCRCC, drying shrinkage and shrinkage cracking of SCRCC reinforced with deformed bars were examined. Test results shows that (1) the free shrinkage of SCRCC is smaller than that of the normal mortar; (2) number of cracks of the restrained specimen made of SCRCC is smaller than that of the normal mortar; and (3) number of cracks in the restrained specimen increases as the reinforcement content increases.
